Problem solving is considered an essential ability for becoming an expert in physics, and individualized feedback on the structure of problem-solving processes is a key component to support students in developing this ability. Problem-solving processes consist of multiple elements whose order forms the sequential structure of these processes.…

In this article, we will present the HEC BB bag, a simple but elegant model originally invented to help students imagine how air molecules move around in vacuum. The HEC BB bag is made by packing 20 to 30 BBs in a resealable plastic bag of several tens of square centimeters (see Fig. 1). When inflated fully via a straw, the volume of the bag is…

Teaching assistants have a very important role in physics education as they interact with students and guide them in different contexts. A multitude of research has focused on how to prepare teaching assistants to implement high-quality, research-based teaching techniques. Video clubs, i.e., working with a group of teachers to watch and discuss…

Estimating astronomical scales requires multiple complex mental processes, such as spatial thinking and interpreting large numbers. As such, it is a nontrivial question how these estimates can be most efficiently assessed. There is reason to believe that results from previous studies probing astronomical scale estimates are possibly susceptible to…

The Energy and Momentum Conceptual Survey (EMCS) is a multiple-choice survey that contains conceptual problems involving a variety of energy and momentum concepts covered in a typical introductory physics course for science and engineering majors. Prior studies suggest that many concepts on the survey are challenging for introductory physics…

In physics education, the topic of electromagnetic induction is an important but also challenging topic for many students. The early introduction of formulae, e.g., Faraday's law of induction, seems to hinder rather than to foster the understanding of the topic's underlying principles. In this paper, we present the basic idea for a teaching…

Inequality in education is a challenge that have persisted and still likely to persist for a long time in the field of education because students come into the classroom with different characteristics thus posing a great concern to the realization of classroom objectives. The use of adequate teaching strategy might break this limitation thereby…

This is potentially the first study that addressed the Puerto Rican high school students' chemistry knowledge acquisition using traditional teaching and Physics Education Technology. The problem addressed by this quantitative comparative quasi-experimental study was that students' showed a disadvantage on chemistry knowledge acquisition over other…

Introductory physics is a gateway course that is required for many science, technology, engineering, and mathematics (STEM) majors. In introductory physics courses, women and racially minoritized students often have lower grades and higher attrition than white men. Inclusive teaching is widely recommended to ensure that all students have the…

In the ever-evolving landscape of education, the integration of Information and Communication Technology (ICT) has emerged as a transformative force, reshaping the way we teach and learn across various disciplines. Among these disciplines, physics stands as a particularly fertile ground for harnessing the power of ICT to enhance teaching…

This study investigates the role of learning dimensions in planning and trialing teaching-learning sequences (TLSs) on surface phenomena in liquids for high school students. Particularly, it aims to identify how different modeling approaches--macroscopic and mesoscopic--impact students' learning in terms of different dimensions of learning such as…

The physics' subject aims to provide the student with a broad understanding of the physical phenomena that occur around them every day and introduce them to the scientific search. The use of experiments in the teaching of the subject contributes to the understanding of these phenomena, the development of skills and critical thinking and has many…

Student learning in simple electric circuits has been an important area in physics education research. This study builds off a previous investigation that applied the conceptual framework model to examine knowledge integration in student learning of simple electric circuits and developed a multiple-choice concept test for assessing knowledge…

The work in this dissertation is presented in two parts. The first part (Chapters 3 and 4) details work relating to students' explanations of reaction mechanisms in organic chemistry. The second part (Chapters 5 and 6) details work relating to the evaluating the uptake of research-based instructional practices in introductory chemistry,…

Higher engineering education programmes increasingly include courses characterised by real-world problems and student collaboration in multidisciplinary teams. Research findings demonstrate that students remain limited in perceiving and meaningfully bridging disciplinary differences in these course contexts. Drawing on the literature on boundaries…
